Answer:
Priya is right.
Step-by-step explanation:
The factors of 80 is 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
The factor pairs of 80 are
1 x 80, 2 x 40, 4 x 20, 5 x 16 and 8 x 10
If Priya picks 2 x 40, then it's prime factorisation will be, 2 x 2 x 2 x 2 x 5 = 2⁴ x 5.
If Han picks, 5 x 16 = 5 x 2 x 2 x 2 x 2 = 5 x 2⁴ = 2⁴ x 5. This is the same.
Therefore, Priya is correct, because the factors of 80 are always the same, therefore which ever you start with, you'd always get the same answer.
The ratio x: y is 1:3
Which of the following statements are correct?
A x is 1/3 of y
B y is 3/4 of (x + y)
x is 1/4 of y
y is 3/4 of x
Answer:
Option A
Step-by-step explanation:
x : y = 1 : 3
This can be also written as
[tex] \frac{x}{y} = \frac{1}{3} [/tex]
Multiplying y on both the sides
[tex] = > \frac{x}{y} \times y = \frac{1}{3} \times y[/tex]
[tex] = > x = \frac{1}{3} \times y[/tex]
Hence , x is one-third of y
Answer:
A and B
x is [tex]\frac{1}{3}[/tex] of y
AND
y is [tex]\frac{3}{4}[/tex] of (x+y)
Step-by-step explanation:
x:y is 1:3
=> y is bigger than x
=> y is 3x bigger than x
=> y = 3 lots of x
=> [tex]y =[/tex] [tex]3x[/tex]
=> [tex]\frac{y}{3}[/tex] [tex]= x[/tex]
=> [tex]\frac{1}{3} y[/tex] [tex]= x[/tex]
So x is [tex]\frac{1}{3}[/tex] of y
y is [tex]\frac{3}{4}[/tex] of (x+y)
If x = 1 and y = 3 (substitute in values)
=> 3 is [tex]\frac{3}{4}[/tex] of (4)
=> 3 is [tex]\frac{3}{4}[/tex](4)
=> 3 is ([tex]\frac{3}{4}[/tex]x4)
=> 3 = 3
Therefore, y is [tex]\frac{3}{4}[/tex] of (x+y) is true
So the answers are:
x is [tex]\frac{1}{3}[/tex] of y
AND
y is [tex]\frac{3}{4}[/tex] of (x+y)
Arlinda is participating in her school reading
challenge. She reads 40 books in 6 months. If 26
of the books are fiction, then what percent of the
books that she read are non-fiction?
Answer:
14
Step-by-step explanation:
40-26=14 so therefore 14% of the books are non-fiction
Bring 8/(a-x) to a denominator of x-a
Answer:
[tex]-\frac{8}{x-a}[/tex]
Step-by-step explanation:
[tex]\frac{8}{a-x}[/tex]
we can take common factor of -1 in the denominator
[tex]\frac{8}{-(-a+x)}=\frac{8}{-(x-a)}[/tex]
and now multiply and divide by -1
[tex]\frac{8}{-(x-a)}\cdot \frac{-1}{-1}=\frac{-8}{x-a}=-\frac{8}{x-a}[/tex]

Sonia has $40 in her lunch account and pays $2 each day to
eat lunch.
How long till her account has no money left?
Answer:
20 days
Step-by-step explanation:
Because to find the number of days that Sonia will have you have to divide total money ($40) by money each day ($2). And $40 divided by $2 is 20, so 20 days is the answer.
Have a most wonderfull day, and I hope you likeee the answer....so yep.

Which expression is equivalent to 13 square root 22b - 10 square root 22b, if b>0?
A. 23 square root 22b
B. 130 square root 22b
C. 3 square root b^2
D. 3 square root 22b
Given:
The expression is
[tex]13\sqrt {22b}-10\sqrt{22b}, b>0[/tex]
To find:
The equivalent expression.
Solution:
We have,
[tex]13\sqrt {22b}-10\sqrt{22b}[/tex]
Taking out common factors.
[tex]=(13-10)\sqrt {22b}[/tex]
[tex]=(3)\sqrt {22b}[/tex]
[tex]=3\sqrt {22b}[/tex]
The expression [tex]3\sqrt {22b}[/tex] is equivalent to the given expression.
Therefore, the correct option is D.

Answer:
2. chord theorem; t = 10.5
3. chord theorem; x = 5
Step-by-step explanation:
For both of these problems, the relevant theorem is the "intersecting chord theorem", also referred to as the "chord theorem." It tells you the product of the lengths of the parts of one chord is equal to the product of the lengths of the parts of the other chord.
2. 20t = 10·21

A recipe code lasagna calls for 3 pounds of tomatoes to serve 5 people. A caterer wants to make enough lasagna to serve 110 people. How many pounds of tomatoes does he neeed
Answer:
66 pounds of tomatoes
Step-by-step explanation:
A recipe code lasagna calls for 3 pounds of tomatoes to serve 5 people. A caterer wants to make enough lasagna to serve 110 people. How many pounds of tomatoes does he neeed
From the above question:
5 people = 3 pounds of tomatoes
110 people = x pounds of tomatoes
Cross Multiply
5 people × x pounds = 110 people × 3 pounds
x pounds = 110 people × 3 pounds/5 people
x pounds = 66 pounds of tomatoes

If y is a positive integer, for how many different values of y is [tex]\sqrt[3]{144\y}[/tex]a whole number?
Answer:
2
Explanation:
I'll explain later, it has to do with prime factors, and perfect cubes.
The two values of y that work are 18, and 144.
³√(144/18) = ³√(8) = 2 [whole number]
³√(144/144) = ³√(1) = 1 [whole number]
